Transmission Line Stringing Tools Anti-vibration Hammer for
Conductor
Stockbridge dampers are designed to reduce wind-induced vibration
of wires. The cable accessory is an indispensable part of overhead
transmission lines. As a professional manufacturer of cables and
cable accessories, we can provide you with specific and complete
advice on cable accessories to ensure the integrity of the entire
electrical system.
We are dedicated to the production and research of global power
supply. Because only high-quality cables and cable accessories have
production value.

Spacer Damper FD Serie
Adopting a preform structure, the clamping strength between the
preform installation damper and the conductor is evenly distributed
at a distance of 30-60cm in the length area. It can effectively
protect conductors and avoid conductor stress concentration.
FD series interval damper uses the rotation and swing of the
hammers at both ends to generate the rated frictional damping
force, so that the galvanized iron wire strands slide against each
other and consume swing energy.
Stockbridge Damper Instructions/Descrption
Common anti-vibration methods include installing Stockbridge
dampers, damper wires, or a combination of Stockbridge dampers and
damper wires. High-frequency vibrations are mainly damped by
damping wires, and low-frequency vibrations are mainly damped by
anti-vibration dampers. Due to the small span and the low
suspension point of the wire, the ordinary span wire generally uses
an anti-vibration hammer to prevent vibration. When vibrating, the
wire drives the anti-vibration hammer to vibrate together, and the
vibration energy of the wire is absorbed by the anti-vibration
hammer, thereby protecting the anti-vibration and anti-vibration of
the transmission line wire.
Due to the long vibration time under strong wind conditions, it is
required to limit the amplitude to a low level, and the amplitude
should not exceed 50% of the normal gear. Generally, a combination
of damping wire and shock absorber is used. In addition, in some
areas where wind vibration conditions are particularly severe,
Stockbridge dampers cannot meet the requirements, and damping wires
and Stockbridge dampers must be used to suppress wind vibration.
